There's barely any clag coming off the top of the 37 in game where as real life you get quite alot with a dark cloud.
There is a youtube video to that. On this 37 is clealy something wrong. The loco could only produce minimum power. From the sound i thought the engine will rip off the frame and land in the next field . There are also flames coming out. A warm engine in certain temperatures / weather condition wont make diesel fumes like in the video. I managed to get it on the cl31 in tsw, not sure it was because the set temperature.
